I successfully installed xAMPP in my local XP Pro.
Now I need to install a PHP script in my website. But according to the script readme, I need to chmod777 (Gives anonymous all access) several of its directories and files.

How can I successfully CHMOD 777 in XP-OS with FAT32?
-vZ

My Efforts & Progress:1. Uncheck "Simple file sharing" in folder options, to make the "sharing tab" appear in file properties
** But that only applies to directories, not the individual files.

2. There is a way to display the SECURITY tab according to [ HERE ]** But it says it is for NTFS partition only. How about if my root is in FAT32 Partition?

3. Use "CACLS" in command line
** Haven't tried, is this really the answer?

4. Use IIS and setup the IUSR_*machine name* account permission
**This might work, but with IIS. How about Apache users?

You can't directly in windows.
Just connect via FileZilla (if you installed xampp, not mini-xampp) to you website and right-click on folder or file you need to chmod. Voila, here you can change mod any way yopu need.
